答案1
\parbox您的章节标题由以下行设置
\hbox{\hspace*{3pt}\parbox{%
\dimexpr\textwidth-2mm-6pt-\chapter@number@width-\tabcolsep-2\fboxrule-20pt}%
{\Huge\bfseries\scshape #1}}
因此添加\raggedright字体即可获得
\hbox{\hspace*{3pt}\parbox{%
\dimexpr\textwidth-2mm-6pt-\chapter@number@width-\tabcolsep-2\fboxrule-20pt}%
{\Huge\bfseries\scshape\raggedright #1}}
